Room For Improvement

The ROI they have given us is tremendous, and they are doing really well in terms of product, scalability, and service.

IT Project Manager at Brilliant telecommunications
To convince my clients, a purely on-prem solution would be ideal since they are financial institutions.
CTO at Malam Engineering PLC
Maybe Imperva DDoS could use endpoints to get information about the attacks before they commence from the endpoint level or establish cooperation with endpoint vendors to share this information.

the setup cost was high, with the hardware installation in the data center being particularly expensive.

Valuable Features

Barracuda WAF-as-a-Service offers real-time security, DDoS protection, and ease-of-use, reducing operational burden with automated features.
Imperva Application Security Platform offers robust threat protection, user-friendly interface, and comprehensive reporting for enhanced web security management.
The centralized dashboard is helping us streamline visibility across our admin panels and provides site-to-site visibility deployed directly to our AWS environment, securing VPC traffic and ensuring the firewall is in place.
Devops Manager at Flash
One of the strongest points is the speed of deployment, which features a three-step deployment wizard, pre-built templates, and quick onboarding, making it suitable for teams that want protection fast without complex infrastructure setup.
Security Practitioner at a tech vendor with 10,001+ employees
I particularly appreciate its ability to automatically detect and block common web attacks such as SQL injection, XSS, and bot-based threats without requiring manual intervention.
network security engineer at a outsourcing company with 11-50 employees
The API security feature is particularly valuable because most attackers do not try to come in from where it is expected.
Senior Cybersecurity Consultant at Cyberoutcome Limited
If someone attempts to access the server, the WAF blocks that SSRF alert, or RCE, Remote Code Execution alert, blocking immediately based on the signature, not only by the payload or the IP address.

It reduces the DDoS attacks and reduces the attacks from threat actors, including SQL Injection and zero-day attacks, by using dynamic application profiling from Imperva.

Featured Reviews

Samir Paul - PeerSpot reviewer
Security Practitioner at a tech vendor with 10,001+ employees
Cloud WAF has protected critical web apps and APIs and delivers fast bot and DDoS defense
Regarding improvements for Barracuda WAF-as-a-Service, the UI and user experience can feel dated. While the interface is functional and centralized, some third-party reviews indicate that the UI can feel outdated, and enhancements are required to provide an executive look that can be aligned with modern and intuitive next-generation competitors. The licensing and cost structure perspective may need clear planning. Barracuda service is customizable but external references note that licensing and cost planning can become complex. Advanced analytics and executive reporting could be better. The platform provides visibility and compliance reporting but organizations looking for a very polished executive dashboard, deep attack visualization, or broader cloud-native security context may find it more focused on WAF operation. Barracuda WAF-as-a-Service is best suited for app and API protection and is not a full CNAPP platform. It is strong for application layer protection but is not positioned as a full CNAPP covering posture management. Modernizing the UI further, simplifying packaging and licensing clarity, enhancing the executive reporting and risk dashboard, and expanding broader cloud-native integration would be beneficial improvements.

Senior Associate at a tech vendor with 10,001+ employees
Application protection has improved and reporting and dashboards still need refinement
I believe Imperva Application Security Platform should have a more interactive wizard. While the dashboard is good, it could be more eye-catching. Based on my perspective, I recommend modifying the dashboards, especially the main dashboard where I can see the traffic hit count, alerts, and other latest information. In terms of reporting, I find it challenging to create reports; in my earlier days, it was difficult. Over time, I have learned how to create reports, but it should be easier to do so. I have used other tools such as firewalls or SolarWinds, where creating a report is straightforward and does not take much time, unlike in Imperva, where I have to add many elements. Modifications in the integration aspects would also be beneficial.
